Black pearls are the crystallization of the hardest years, rare and noble after suffering.
Black pearls are the most painful tears of the mother-of-pearl, and the mysterious luster that flows around never makes people easily peep into the mind.
The black pearl is the most elegant elf in the sea. It is printed with deep sea colors. It seems that there are waves, but it can't see the stable appearance.
Legend has it that when a drop of dew drops into the sea, if it is just caught by an open seashell, it can form a crystal pearl. If the weather is not good, the dewdrops under the gray sky fall into the seashells, forming a black pearl.
This legend has been passed down from the 15th century to the present, and people feel that the black pearl is the tear when the sky is sad, so the color is deep and dignified, not like the lightness and clarity of ordinary white pearls.
Another legend is more beautiful. The god of peace and richness, Oro, came to the world with a rainbow, and dedicated the pearl of the pearl, TeUfi, to humans. TeUfi is the mother of black pearls.
In short, that mysterious and noble black pearl comes from the gods and is the treasure of heaven and earth.
At present, Black Pearl has only two major natural origins: one is the Tahitian island of the Polynesian Islands, which produces 95% of the world's black pearls; the other is the Penglin Island and Majuhiki Island of the Cook Islands, which account for the total output. 4%. These two regions live together in the south-central Pacific Ocean, so it is also known as the Black Pearl.
The pearl frit, which produces black pearls, is a black butterfly that secretes black pearls. The beauty of the black pearl is that it has a variety of colors on the black tone of the natural world. The most appreciated are the rainbow colors such as malachite green, rich purple and sea blue. Its strong metallic luster changes with the rotation of the pearl, not the other. Color-changing pearls can be compared.
The annual production of quality black pearls is estimated to be no more than 150,000, of which 40% are sold through the annual international auction. Most black pearls have a particle size between 9mm and 10mm, and more than 60% of the black pearls have a particle size of no more than 11mm. Therefore, 11mm is generally regarded as the limit of the treasure of black pearls, and the fine round black pearl of 15mm or more is very rare, and even the ready-made products can be referred to the market price, which shows that it is expensive and rare.
In ancient China, black pearls represented wisdom. It is guarded between the dragon's teeth, giving off a seductive luster. But whoever wants to get it, whoever wants to conquer the dragon. The dragon's hugeness and divine power are daunting, so those who can conquer the dragon must have extraordinary wisdom, so that they are worthy of the black pearl.
Aluminum Auto die casting parts/ truck parts
Description:
Passive one does not use any mechanical components and the heat can be dissipated through convection or transferred through liquid or gas caused by molecular motion.Our aluminum heat sink is used to absorb thermal energy or heat from another object through thermal compounds which are also known as thermally conductive materials. At a relatively high temperature, the heat is absorbed from the object and transferred to the heat sink which has a much larger heat capacity. Being a practical thermal energy solution for both low and high volumes, extruded aluminum heat sink is widely applied for heat radiation of refrigerators, engines, medical devices, lasers, cpus, etc. These applications are quite helpful in such industries as electronics, medical equipment, industrial manufacturing, household appliance, led lighting, and military industry, etc.
